re PR target/49780 ([x32] internal compiler error: in create_mem_ref, at tree-ssa-address.c:806)
PR target/49780
* config/i386/predicates.md (no_seg_addres_operand): No more special.
* config/i386/i386.c (ix86_decompose_address): Allow only subregs
of DImode hard registers in base.
(ix86_legitimate_address_p): Allow SImode and DImode base and index
registers.
